13 Panel Drug Test Cups, Bulk Cases

What a 13-panel test covers

A twelve-panel set plus one more — commonly tricyclics, or one of the forensic analytes below. Eight configurations across integrated and compact cups.

EtG, fentanyl and tramadol

Several thirteen-panel configurations include EtG (a marker of alcohol consumption over roughly 80 hours, far longer than a breath test), fentanyl, or tramadol. These are the analytes worth paying for at this count — they are what a twelve-panel screen misses.

Regulatory status — read this before ordering

Any configuration including EtG, fentanyl, tramadol or K2 is For Forensic Use Only. That means not for clinical diagnosis and not for employment testing. The configurations without those analytes are CLIA-waived. The panel count does not tell you which — each product states its status.

Ordering

Cups are sold by the box of 25 tests.

Who orders thirteen-panel screens

At thirteen analytes the buyer is nearly always a program with a written, reviewed testing protocol rather than a general workplace policy: treatment and recovery services, pain-management practices monitoring adherence, drug courts and community-supervision programs, and laboratories running a confirmatory workflow behind the screen. The order is normally placed by a program or laboratory manager against that protocol document, and it gets revisited when the protocol is revisited rather than in between.

Thirteen is a family, not a single product

More than at any other count on this site, thirteen-panel describes a group of configurations rather than one item. The versions stocked here differ from one another in which analytes occupy the last few positions, and those differences are the whole reason a program picked one over another. Reading the analyte list on the individual product page is not optional at this count — the number on the label will not tell you what is on the strip.

Comparing and ordering

Read this page alongside the 12-panel below it and the 14-panel above it, or start from the full range on drug test cups. Programs that also need to send samples on will find containers, transport bags and tubes under specimen collection.

Before you reorder

Check two things against the last order rather than against the category: the analyte list for the exact configuration, and the format, since the same count is sold here in more than one cup style. Changing one without meaning to is the most common way a delivery matches the purchase order and still is not what the site expected.
